Frequently asked questions

Network Rail’s East Coast Upgrade is a £1.2 billion plan that covers a number of different improvements along the East Coast Main Line, which is a key rail route that connects London with Cambridge and Peterborough and beyond to Yorkshire, the North East of England and Scotland.
The work includes a major upgrade at King’s Cross station bringing a disused tunnel back into use, upgrading overhead wires and construction of almost 2km of new railway line. It also involves the transfer of the signalling control from King’s Cross signal box to the modern Rail Operations Centre in York.

The East Coast Upgrade creates a new, simpler, layout at King’s Cross with additional tracks allowing an increase in capacity, while the new equipment being installed will mean fewer delays.
The control of the signalling in and out of Moorgate is being transferred to York as part of the East Coast upgrade.

Because of this, sometimes the lines to and from Moorgate will need to be closed at the same time as the route in and out of King’s Cross to allow the works to take place safely.
We know that closing the railway to carry out improvement work has a big impact on customers, which is why we work hard with Network Rail and other train companies to plan the work in a way that minimises overall disruption as much as possible. We hope that by providing advanced information people will be able to make informed choices and be more flexible with their travel plans.
The work will continue until June 2021 meaning we may have to close parts of the line, including on some Fridays and at weekends. These will be advertised in advance to allow you to plan ahead. Keep checking back here or visit eastcoastupgrade.co.uk for the latest information.
Customers at these stations have alternative Transport for London bus, underground and rail routes. The Northern and Piccadilly lines run close to most of the affected stations.
Bikes can be taken on alternative rail routes (subject to normal time restrictions) but only fold-up bikes can be taken on replacement buses.

If your journey involves using London Underground or TfL Buses, please check here before you travel.
If you need step-free access for your journey, please speak to a member of station staff or contact our Assisted Travel team on 0800 058 2844.

Keep checking back here for train service information, or visit www.eastcoastupgrade.co.uk for updates on the upgrade works.
A new platform has been built at Stevenage for our services to use. This means Hertford North line trains no longer get in the way of other services going up and down the line, so reducing delays.

Separate projects to renovate stations and to clean the tunnels have now largely been completed.
